FIELD OF THE INVENTION

The present invention relates to methods of developing geneticallyengineered, preferably non-alloreactive, immune cells for immunotherapy,which are endowed with Chimeric Antigen Receptors targeting an antigenmarker that is common to both the pathological cells and the immunecells (ex: CD38).

10 The method comprises expressing a CAR directed against said antigenmarker and inactivating the genes in the immune cells contributing tothe presence of said antigen marker on the surface of said immune cells.This inactivation is typically performed by using transgenes encodingRNA-guided endonucleases (ex: Cas9/CRISPR), meganucleases, Zinc-fingernucleases or TAL nucleases. The engineered immune cells, preferablyT-cells, direct their immune activity towards malignant, infected cellsor defective immune cells, while avoiding their mutual destruction,auto-stimulation or aggregation. The invention opens the way to standardand affordable adoptive immunotherapy strategies using immune cells fortreating cancer, infections and auto-immune diseases.

BACKGROUND OF THE INVENTION

Adoptive immunotherapy, which involves the transfer of autologousantigen-specific immune cells generated ex vivo, is a promising strategyto treat viral infections and cancer. The T cells used for adoptiveimmunotherapy, for instance, can be generated either by expansion ofantigen-specific T-cells or redirection of T-cells through geneticengineering (Park, Rosenberg et al. 2011).

Novel specificities in T-cells have been successfully generated throughthe genetic transfer of transgenic T-cell receptors or chimeric antigenreceptors (CARs) (Jena, Dotti et al. 2010). CARs are synthetic receptorsconsisting of a targeting moiety that is associated with one or moresignaling domains in a single fusion molecule. In general, the bindingmoiety of a CAR consists of an antigen-binding domain of a single-chainantibody (scFv), comprising the light and variable fragments of amonoclonal antibody joined by a flexible linker. Binding moieties basedon receptor or ligand domains have also been used successfully. Thesignaling domains for first generation CARs are derived from thecytoplasmic region of the CD3zeta or the Fc receptor gamma chains. Firstgeneration CARs have been shown to successfully redirect T cellcytotoxicity, however, they failed to provide prolonged expansion andanti-tumor activity in vivo. Signaling domains from co-stimulatorymolecules including CD28, OX-40 (CD134), and 4-1BB (CD137) have beenadded alone (second generation) or in combination (third generation) toenhance survival and increase proliferation of CAR modified T cells.CARs have successfully allowed T cells to be redirected against antigensexpressed at the surface of tumor cells from various malignanciesincluding lymphomas and solid tumors (Jena, Dotti et al. 2010).

The current protocol for treatment of patients using adoptiveimmunotherapy is based on autologous cell transfer. In this approach, Tlymphocytes are recovered from patients, genetically modified orselected ex vivo, cultivated in vitro in order to amplify the number ofcells if necessary and finally infused into the patient. In addition tolymphocyte infusion, the host may be manipulated in other ways thatsupport the engraftment of the T cells or their participation in animmune response, for example pre-conditioning (with radiation orchemotherapy) and administration of lymphocyte growth factors (such asIL-2). Each patient receives an individually fabricated treatment, usingthe patient's own lymphocytes (i.e. an autologous therapy). Autologoustherapies face substantial technical and logistic hurdles to practicalapplication, their generation requires expensive dedicated facilitiesand expert personnel, they must be generated in a short time following apatient's diagnosis, and in many cases, pretreatment of the patient hasresulted in degraded immune function, such that the patient'slymphocytes may be poorly functional and present in very low numbers.Because of these hurdles, each patient's autologous cell preparation iseffectively a new product, resulting in substantial variations inefficacy and safety.

Ideally, one would like to use a standardized therapy in whichallogeneic therapeutic cells could be pre-manufactured, characterized indetail, and available for immediate administration to patients. Byallogeneic it is meant that the cells are obtained from individualsbelonging to the same species but are genetically dissimilar. However,the use of allogeneic cells presently has many drawbacks. Inimmune-competent hosts allogeneic cells are rapidly rejected, a processtermed host versus graft rejection (HvG), and this substantially limitsthe efficacy of the transferred cells. In immune-incompetent hosts,allogeneic cells are able to engraft, but their endogenous T-cellreceptors (TCR) specificities may recognize the host tissue as foreign,resulting in graft versus host disease (GvHD), which can lead to serioustissue damage and death.

In order to provide allogeneic T-cells, the inventors previouslydisclosed a method to genetically engineer T-Cells, in which differenteffector genes, in particular those encoding T-cell receptors, wereinactivated by using specific TAL-nucleases, better known under thetrade mark TALEN™ (Cellectis, 8, rue de la Croix Jarry, 75013 PARIS).This method has proven to be highly efficiency in primary cells usingRNA transfection as part of a platform allowing the mass production ofallogeneic T-cells (WO 2013/176915).

CD38 (cluster of differentiation 38), also known as cyclic ADP ribosehydrolase is a glycoprotein found on the surface of many immune cells(white blood cells),in particular T-cells, including CD4+, CD8+, Blymphocytes and natural killer cells. CD38 also functions in celladhesion, signal transduction and calcium signaling. Structuralinformation about this protein can be found in the UniProtKB/Swiss-Protdatabase under reference P28907. In humans, the CD38 protein is encodedby the CD38 gene which located on chromosome 4. CD38 is amultifunctional ectoenzyme that catalyzes the synthesis and hydrolysisof cyclic ADP-ribose (cADPR) from NAD+ to ADP-ribose. These reactionproducts are deemed essential for the regulation of intracellular Ca2+.Also, loss of CD38 function was associated with impaired immuneresponses and metabolic disturbances (Malavasi F., et al. (2008).“Evolution and function of the ADP ribosyl cyclase/CD38 gene family inphysiology and pathology”. Physiol. Rev. 88(3): 841-86).

On another hand, CD38 protein is a marker of HIV infection, leukemias,myelomas, solid tumors, type II diabetes mellitus and bone metabolism,as well as some other genetically determined conditions. In particular,it has been used as a prognostic marker in leukemia (Ibrahim, S. et al.(2001) CD38 expression as an important prognostic factor in B-cellchronic lymphocytic leukemia. Blood 98:181-186).

Although, cells expressing CD38, as well as many other tumor antigenmarkers referred to in Table 1, such as CD70 and CS1 could be regardedas attractive targets for CARs, the fact that such antigen markers arealso expressed at the surface of most T-cells, has hamperedsignificantly the selection of these markers to perform immunotherapy.

The inventors here provide strategies for immunotherapy involvingpathological cells expressing specific antigen markers also present atthe surface of T-cells, like for instance malignant CD38 positiveB-cells causing leukemia, CD70 and CS1.

SUMMARY OF THE INVENTION

The present invention discloses methods to engineer T-cells intended totarget pathological cells, whereas said pathological cells express oneor several antigen markers that are also present on the surface ofT-cells. Examples of such antigen markers are found in Table 1. Anexample of such antigen marker is CD38. Other examples are CD70 and CS1.By antigen marker is meant the whole protein of an immune-reactivefragment thereof.

According to the invention, the T-cells are engineered in order toinactivate the expression of the genes encoding such antigen markers, orinvolved into the presentation of such antigen marker on the cellsurface.

This inactivation is preferably performed by a genome modification, moreparticularly through the expression in the T-cell of a specificrare-cutting endonuclease able to target a genetic locus directly orindirectly involved in the production or presentation of said antigenmarker at the surface of the T-cell. Different types of rare-cuttingendonucleases can be used, such as Meganucleases, TAL-nucleases,zing-finger nucleases (ZEN), or RNA/DNA guided endonucleases likeCas9/CRISPR or Argonaute.

According to a preferred embodiment, the T-cells are endowed with atleast one chimeric antigen receptors (CAR) allowing a specific bindingof said cells bearing said targeted antigen marker.

According to another embodiment, the T-cells can be further engineeredto make them allogeneic, especially by deleting genes involved intoself-recognition, such as those, for instance, encoding components ofT-cell receptors (TCR) or HLA complex.

The present invention encompasses the isolated cells or cell linescomprising the genetic modifications set forth in the detaileddescription, examples and figures, as well as any of the proteins,polypeptides or vectors useful to engineer said T-cells.

As a result of the invention, the engineered T-cells can be used astherapeutic products, ideally as an “off the shelf” product, in methodsfor treating or preventing cancer, infections or auto-immune disease.

Preferred immune cells according to the present invention are thoseresulting into the phenotypes:

-   -   [CAR targeting a antigen marker of Table1]⁺ [antigen marker of        Table1]⁻ such as the following ones:    -   [CAR CD38]⁺[CD38]⁻, preferably also [TCR] negative;    -   [CAR CD70]⁺[CD70]⁻, preferably also [TCR] negative;    -   [CAR CS1]⁺[CS1]⁻, preferably also [TCR] negative;        for their use as therapeutic products, preferably allogeneic        ones.

In a general aspect, the present invention relates to methods for newadoptive immunotherapy strategies in treating diseases linked with thedevelopment of pathological cells, such as cancer, infections andauto-immune diseases.

As a main objective of the invention is the possibility to targetpathological cells that bear specific antigen markers in common withT-cells. By pathological cell is meant any types of cells present in apatient, which are deemed causing health deterioration.

In general, pathological cells are malignant or infected cells that needto be reduced or eliminated to obtain remission of a patient.

In a first embodiment, the method of the invention concerns a method ofpreparing appropriate immune cells, preferably T-cells for immunotherapycomprising the step of:

-   -   (a) Genetically inactivating or mutating a gene in an immune        cell, which is involved in the expression or presentation of an        antigen marker, said antigen marker being known to be present        both on the surface of said T-cell and the pathological cell;    -   (b) Expressing into said immune cell a transgene encoding a        chimeric antigen receptor directed against said antigen marker        present at the surface of said pathological cell.

The immune cells according to the invention are endowed with a chimericantigen receptor directed to an antigen marker that is commonlyexpressed by the pathological cells and immune cells, or known to bepresent on the surface of said T Cells. The expression “known to bepresent” means that the antigen marker is reported to be found on thesurface of the immune cells grown in natural conditions in-vivo,especially in the blood, but not necessarily when they are culturedin-vitro. In any event, the method of the invention results into theabsence of the antigen marker on the surface of the immune cell, therebypreventing the chimeric antigen receptor from reacting with theengineered T-cell surface. In this respect, the method may include afurther step of purifying the resulting T-cells by excluding the cellspresenting said marker antigen on their surface.

As shown in Table 4, this invention relates to an important number ofantigen marker candidates reported to be expressed by tumor cells, butalso by T-cells. Some of them, like CD38, have been used as specificmarkers in diagnostic methods for a while, especially with respect toLeukemia pathological cells, but not in therapy. Indeed, although thesemarkers were identified in the art as quite specific markers, they couldnot be used as targets for immunotherapy because antibodies directedagainst these markers would have destroyed or interfered with patients'T-cells. The present inventors have established that CS1 and CD70 arealso present on the surface of T-cells and that expressing CARstargeting CS1 and CD70 in such T cells leads to their depletion (seeexample 2).

According to a preferred embodiment of the invention, the gene mutationor inactivation of step a) of the above method is performed using arare-cutting endonuclease.

By inactivating a gene it is intended that the gene of interest is notexpressed in a functional protein form. In particular embodiments, thegenetic modification of the method relies on the expression, in providedcells to engineer, of a rare-cutting endonuclease such that samecatalyzes cleavage in one targeted gene thereby inactivating saidtargeted gene. The nucleic acid strand breaks caused by the endonucleaseare commonly repaired through the distinct mechanisms of homologousrecombination or non-homologous end joining (NHEJ). However, NHEJ is animperfect repair process that often results in changes to the DNAsequence at the site of the cleavage. Mechanisms involve rejoining ofwhat remains of the two DNA ends through direct re-ligation (Critchlowand Jackson 1998) or via the so-called microhomology-mediated endjoining (Betts, Brenchley et al. 2003; Ma, Kim et al. 2003). Repair vianon-homologous end joining (NHEJ) often results in small insertions ordeletions and can be used for the creation of specific gene knockouts.Said modification may be a substitution, deletion, or addition of atleast one nucleotide. Cells in which a cleavage-induced mutagenesisevent, i.e. a mutagenesis event consecutive to an NHEJ event, hasoccurred can be identified and/or selected by well-known method in theart.

The term “rare-cutting endonuclease” refers to a wild type or variantenzyme capable of catalyzing the hydrolysis (cleavage) of bonds betweennucleic acids within a DNA or RNA molecule, preferably a DNA molecule.Particularly, said nuclease can be an endonuclease, more preferably arare-cutting endonuclease which is highly specific, recognizing nucleicacid target sites ranging from 10 to 45 base pairs (bp) in length,usually ranging from 10 to 35 base pairs in length, more usually from 12to 20 base pairs. The endonuclease according to the present inventionrecognizes at specific polynucleotide sequences, further referred to as“target sequence” and cleaves nucleic acid inside these target sequencesor into sequences adjacent thereto, depending on the molecular structureof said endonuclease. The rare-cutting endonuclease can recognize andgenerate a single- or double-strand break at specific polynucleotidessequences.

In a particular embodiment, said rare-cutting endonuclease according tothe present invention is a RNA-guided endonuclease such as theCas9/CRISPR complex. RNA guided endonucleases constitute a newgeneration of genome engineering tool where an endonuclease associateswith a RNA molecule. In this system, the RNA molecule nucleotidesequence determines the target specificity and activates theendonuclease (Gasiunas, Barrangou et al. 2012; Jinek, Chylinski et al.2012; Cong, Ran et al. 2013; Mali, Yang et al. 2013).

Cas 9

Cas9, also named Csn1 (COG3513) is a large protein that participates inboth crRNA biogenesis and in the destruction of invading DNA. Cas9 hasbeen described in different bacterial species such as S. thermophiles,Listeria innocua (Gasiunas, Barrangou et al. 2012; Jinek, Chylinski etal. 2012) and S. Pyogenes (Deltcheva, Chylinski et al. 2011). The largeCas9 protein (>1200 amino acids) contains two predicted nucleasedomains, namely HNH (McrA-like) nuclease domain that is located in themiddle of the protein and a splitted RuvC-like nuclease domain (RNase Hfold) (Makarova, Grishin et al. (2006).

By “Cas9” is meant an engineered endonuclease or a homologue of Cas9which is capable of processing target nucleic acid sequence. Inparticular embodiment, Cas9 can induce a cleavage in the nucleic acidtarget sequence which can correspond to either a double-stranded breakor a single-stranded break. Cas9 variant can be a Cas9 endonuclease thatdoes not naturally exist in nature and that is obtained by proteinengineering or by random mutagenesis. Cas9 variants according to theinvention can for example be obtained by mutations i.e. deletions from,or insertions or substitutions of at least one residue in the amino acidsequence of a S. pyogenes Cas9 endonuclease (COG3513). In the frameaspects of the present invention, such Cas9 variants remain functional,i.e. they retain the capacity of processing a target nucleic acidsequence. Cas9 variant can also be homologues of S. pyogenes Cas9 whichcan comprise deletions from, or insertions or substitutions of, at leastone residue within the amino acid sequence of S. pyogenes Cas9. Anycombination of deletion, insertion, and substitution may also be made toarrive at the final construct, provided that the final constructpossesses the desired activity, in particular the capacity of binding aguide RNA or nucleic acid target sequence.

RuvC/RNaseH motif includes proteins that show wide spectra ofnucleolytic functions, acting both on RNA and DNA (RNaseH, RuvC, DNAtransposases and retroviral integrases and PIWI domain of Argonautproteins). In the present invention the RuvC catalytic domain of theCas9 protein can be characterized by the sequence motif:D-[I/L]-G-X-X-S-X-G-W-A, wherein X represents any one of the natural 20amino acids and [I/L] represents isoleucine or leucine. In other terms,the present invention relates to Cas9 variant which comprises at leastD-[I/L]-X-X-S-X-G-W-A sequence, wherein X represents any one of thenatural 20 amino acids and [I/L] represents isoleucine or leucine.

HNH motif is characteristic of many nucleases that act ondouble-stranded DNA including colicins, restriction enzymes and homingendonucleases. The domain HNH (SMART ID: SM00507, SCOP nomenclature:HNHfamily) is associated with a range of DNA binding proteins, performing avariety of binding and cutting functions. The ones with known functionare involved in a range of cellular processes including bacterialtoxicity, horning functions in groups I and II introns and inteins,recombination, developmentally controlled DNA rearrangement, phagepackaging, and restriction endonuclease activity (Dalgaard, Klar et al.1997). These proteins are found in viruses, archaebacteria, eubacteria,and eukaryotes. Interestingly, as with the LAGLI-DADG and the GIY-YIGmotifs, the HNH motif is often associated with endonuclease domains ofself-propagating elements like inteins, Group I, and Group II introns(Dalgaard, Klar et al. 1997). The HNH domain can be characterized by thepresence of a conserved Asp/His residue flanked by conserved His(amino-terminal) and His/Asp/Glu (carboxy-terminal) residues at somedistance. A substantial number of these proteins can also have a CX2Cmotif on either side of the central Asp/His residue. Structurally, theHNH motif appears as a central hairpin of twisted β-strands, which areflanked on each side by an a helix (Kleanthous, Kuhlmann et al. 1999).The large HNH domain of Cas9 is represented by SEQ ID NO.5. In thepresent invention, the HNH motif can be characterized by the sequencemotif: Y-X-X-D-H-X-X-P-X-S-X-X-X-D-X-S, wherein X represents any one ofthe natural 20 amino acids. The present invention relates to a Cas9variant which comprises at least Y-X-X-D-H-X-X-P-X-S-X-X-X-D-X-Ssequence wherein X represents any one of the natural 20 amino acids.

This invention can be of particular interest to easily do targetedmultiplex gene modifications and to create an inducible nuclease systemby introduction of the guide RNA to the Cas9 cells. For the purpose ofthe present invention, the inventors have established that Cas9 proteincan be divided into two separate split Cas9 RuvC and HNH domains whichcan process target nucleic acid sequence together or separately with theguide RNA.

Also the RuvC and HNH domains from different RNA guided endonucleases orCas homologues may be assembled to improve nuclease efficiency orspecificity. The domains from different species can be either split intotwo proteins or fused to each other to form a variant Cas protein. TheCas9 split system is deemed particularly suitable for an induciblemethod of genome targeting and to avoid the potential toxic effect ofthe Cas9 overexpression within the cell. Indeed, a first split Cas9domain can be introduced into the cell, preferably by stablytransforming said cell with a transgene encoding said split domain.Then, the complementary split part of Cas9 can be introduced into thecell, such that the two split parts reassemble into the cell toreconstitute a functional Cas9 protein at the desired time.

The reduction of the size of the split Cas9 compared to wild type Cas9ease the vectorization and the delivery into the cell, for example, byusing cell penetrating peptides. Re-arranging domains from different Casproteins, allows to modulate the specificity and nuclease activity, forinstance, by targeting PAM motifs that are slightly different from S.pyogenes Cas9

Split Cas9 System

The previous characterization of the RuvC and HNH domains has promptedthe inventors to engineer Cas9 protein to create split Cas9 protein.Surprisingly, the inventors showed that these two split Cas9 couldprocess together or separately the nucleic acid target. This observationallows developing a new Cas9 system using split Cas9 protein. Each splitCas9 domains can be prepared and used separately. Thus, this splitsystem displays several advantages for vectorization and delivery of theRNA guided endonuclease in T-cells, allowing delivering a shorter and/orinactive protein, and is particularly suitable to induce genomeengineering in T-cells at the desired time and thus limiting thepotential toxicity of an integrated Cas9 nuclease.

By “Split Cas9” is meant here a reduced or truncated form of a Cas9protein or Cas9 variant, which comprises either a RuvC or HNH domain,but not both of these domains. Such “Split Cas9” can be usedindependently with guide RNA or in a complementary fashion, like forinstance, one Split Cas9 providing a RuvC domain and another providingthe HNH domain. Different split RNA guided endonucleases may be usedtogether having either RuvC and/or NHN domains.

Each Cas9 split domain can be derived from the same or from differentCas9 homologues. Many homologues of Cas9 have been identified in genomedatabases.

Said Cas9 split domains (RuvC and HNH domains) can be simultaneously orsequentially introduced into the cell such that said split Cas9domain(s) process the target nucleic acid sequence in the cell. SaidCas9 split domains and guide RNA can be introduced into the cell byusing cell penetrating peptides or other transfection methods asdescribed elsewhere.

In another aspect of the invention, only one split Cas9 domain, referredto as compact Cas9 is introduced into said cell. Indeed, surprisinglythe inventors showed that the split Cas9 domain comprising the RuvCmotif as described above is capable of cleaving a target nucleic acidsequence independently of split domain comprising the HNH motif. Thus,they could establish that the guideRNA does not need the presence of theHNH domain to bind to the target nucleic acid sequence and issufficiently stable to be bound by the RuvC split domain. In a preferredembodiment, said split Cas9 domain alone is capable of nicking saidtarget nucleic acid sequence.

Each split domain can be fused to at least one active domain in theN-terminal and/or C-terminal end, said active domain can be selectedfrom the group consisting of: nuclease (e.g. endonuclease orexonuclease), polymerase, kinase, phosphatase, methylase, demethylase,acetylase, desacetylase, topoisomerase, integrase, transposase, ligase,helicase, recombinase, transcriptional activator(e.g. VP64, VP16),transcriptional inhibitor (e. g; KRAB), DNA end processing enzyme (e.g.Trex2, Tdt), reporter molecule (e.g. fluorescent proteins, lacZ,luciferase).

HNH domain is responsible for nicking of one strand of the targetdouble-stranded DNA and the RuvC-like RNaseH fold domain is involved innicking of the other strand (comprising the PAM motif) of thedouble-stranded nucleic acid target (Jinek, Chylinski et al. 2012).However, in wild-type Cas9, these two domains result in blunt cleavageof the invasive DNA within the same target sequence (proto-spacer) inthe immediate vicinity of the PAM (Jinek, Chylinski et al. 2012). Cas 9can be a nickase and induces a nick event within different targetsequences.

As non-limiting example, Cas9 or split Cas9 can comprise mutation(s) inthe catalytic residues of either the HNH or RuvC-like domains, to inducea nick event within different target sequences. As non-limiting example,the catalytic residues of the Cas9 protein are those corresponding toamino acids D10, D31, H840, H868, N882 and N891 or aligned positionsusing CLUSTALW method on homologues of Cas Family members. Any of theseresidues can be replaced by any other amino acids, preferably by alanineresidue. Mutation in the catalytic residues means either substitution byanother amino acids, or deletion or addition of amino acids that inducethe inactivation of at least one of the catalytic domain of cas9. (cf..In a particular embodiment, Cas9 or split Cas9 may comprise one orseveral of the above mutations. In another particular embodiment, splitCas9 comprises only one of the two RuvC and HNH catalytic domains. Inthe present invention, Cas9 from different species, Cas9 homologues,Cas9 engineered and functional variant thereof can be used. Theinvention envisions the use of any RNA guided endonuclease or split RNAguided endonucleases variants to perform nucleic acid cleavage in agenetic sequence of interest.

Preferably, the Cas9 variants according to the invention have an aminoacid sequence sharing at least 70%, preferably at least 80%, morepreferably at least 90%, and even more preferably 95% identity with Cas9of S. Pyogenes (COG3513).

Meganucleases

Rare-cutting endonuclease can also be a homing endonuclease, also knownunder the name of meganuclease. Such homing endonucleases are well-knownto the art (Stoddard 2005). Homing endonucleases are highly specific,recognizing DNA target sites ranging from 12 to 45 base pairs (bp) inlength, usually ranging from 14 to 40 bp in length. The homingendonuclease according to the invention may for example correspond to aLAGLIDADG endonuclease, to a HNH endonuclease, or to a GIY-YIGendonuclease. Preferred homing endonuclease according to the presentinvention can be an I-Crel variant. A “variant” endonuclease, i.e. anendonuclease that does not naturally exist in nature and that isobtained by genetic engineering or by random mutagenesis can bind DNAsequences different from that recognized by wild-type endonucleases (seeinternational application WO2006/097854).

Said rare-cutting endonuclease can be a modular DNA binding nuclease. Bymodular DNA binding nuclease is meant any fusion proteins comprising atleast one catalytic domain of an endonuclease and at least one DNAbinding domain or protein specifying a nucleic acid target sequence. TheDNA binding domain is generally a RNA or DNA-binding domain formed by anindependently folded polypeptide or protein domain that contains atleast one motif that recognizes double- or single-strandedpolynucleotides. Many such polypeptides have been described in the arthaving the ability to bind specific nucleic acid sequences. Such bindingdomains often comprise, as non-limiting examples, helix-turn helixdomains, leucine zipper domains, winged helix domains, helix-loop-helixdomains, HMG-box domains, Immunoglobin domains, B3 domain or engineeredzinc finger domain.

Zinc-Finger Nucleases

Initially developed to cleave DNA in vitro, “Zinc Finger Nucleases”(ZFNs) are a fusion between the cleavage domain of the type IISrestriction enzyme, FokI, and a DNA recognition domain containing 3 ormore C2H2 zinc finger motifs. The heterodimerization at a particularposition in the DNA of two individual ZFNs in precise orientation andspacing leads to a double-strand break (DSB) in the DNA. The use of suchchimeric endonucleases have been extensively reported in the art asreviewed by Urnov et al. (Genome editing with engineered zinc fingernucleases (2010) Nature reviews Genetics 11:636-646).

Standard ZFNs fuse the cleavage domain to the C-terminus of each zincfinger domain. In order to allow the two cleavage domains to dimerizeand cleave DNA, the two individual ZFNs bind opposite strands of DNAwith their C-termini a certain distance apart. The most commonly usedlinker sequences between the zinc finger domain and the cleavage domainrequires the 5′ edge of each binding site to be separated by 5 to 7 bp.

The most straightforward method to generate new zinc-finger arrays is tocombine smaller zinc-finger “modules” of known specificity. The mostcommon modular assembly process involves combining three separate zincfingers that can each recognize a 3 base pair DNA sequence to generate a3-finger array that can recognize a 9 base pair target site. Numerousselection methods have been used to generate zinc-finger arrays capableof targeting desired sequences. Initial selection efforts utilized phagedisplay to select proteins that bound a given DNA target from a largepool of partially randomized zinc-finger arrays. More recent effortshave utilized yeast one-hybrid systems, bacterial one-hybrid andtwo-hybrid systems, and mammalian cells.

TAL-Nucleases

“TALE-nuclease” or “MBBBD-nuclease” refers to engineered proteinsresulting from the fusion of a DNA binding domain typically derived fromTranscription Activator Like Effector proteins (TALE) or ModularBase-per-Base Binding domain (MBBBD), with a catalytic domain havingendonuclease activity. Such catalytic domain usually comes from enzymes,such as for instance I-Tevl, ColE7, NucA and Fok-I. TALE-nuclease can beformed under monomeric or dimeric forms depending of the selectedcatalytic domain (WO2012138927). Such engineered TALE-nucleases arecommercially available under the trade name TALENT™ (Cellectis, 8 rue dela Croix Jarry, 75013 Paris, France).

According to a preferred embodiment of the invention, the DNA bindingdomain is derived from a Transcription Activator like Effector (TALE),wherein sequence specificity is driven by a series of 33-35 amino acidsrepeats originating from Xanthomonas or Ralstonia bacterial proteinsAvrBs3, PthXo1, AvrHah1, PthA, Tal1c as non-limiting examples.

These repeats differ essentially by two amino acids positions thatspecify an interaction with a base pair (Boch, Scholze et al. 2009;Moscou and Bogdanove 2009). Each base pair in the DNA target iscontacted by a single repeat, with the specificity resulting from thetwo variant amino acids of the repeat (the so-called repeat variabledipeptide, RVD). TALE binding domains may further comprise an N-terminaltranslocation domain responsible for the requirement of a first thyminebase (TO) of the targeted sequence and a C-terminal domain thatcontaining a nuclear localization signals (NLS). A TALE nucleic acidbinding domain generally corresponds to an engineered core TALE scaffoldcomprising a plurality of TALE repeat sequences, each repeat comprisinga RVD specific to each nucleotides base of a TALE recognition site. Inthe present invention, each TALE repeat sequence of said core scaffoldis made of 30 to 42 amino acids, more preferably 33 or 34 wherein twocritical amino acids (the so-called repeat variable dipeptide, RVD)located at positions 12 and 13 mediates the recognition of onenucleotide of said TALE binding site sequence; equivalent two criticalamino acids can be located at positions other than 12 and 13 speciallyin TALE repeat sequence taller than 33 or 34 amino acids long.Preferably, RVDs associated with recognition of the differentnucleotides are HD for recognizing C, NG for recognizing T, NI forrecognizing A, NN for recognizing G or A. In another embodiment,critical amino acids 12 and 13 can be mutated towards other amino acidresidues in order to modulate their specificity towards nucleotides A,T, C and G and in particular to enhance this specificity. A TALE nucleicacid binding domain usually comprises between 8 and 30 TALE repeatsequences. More preferably, said core scaffold of the present inventioncomprises between 8 and 20 TALE repeat sequences; again more preferably15 TALE repeat sequences. It can also comprise an additional singletruncated TALE repeat sequence made of 20 amino acids located at theC-terminus of said set of TALE repeat sequences, i.e. an additionalC-terminal half-TALE repeat sequence.

Other engineered DNA binding domains can be used as alternativesequences to form so-called modular base-per-base specific nucleic acidbinding domains (MBBBD) as described in WO 2014/018601. Said MBBBD canbe engineered, for instance, from newly identified proteins, namelyEAV36_BURRH, E5AW43_BURRH, E5AW45_BURRH and E5AW46_BURRH proteins fromthe recently sequenced genome of the endosymbiont fungi BurkholderiaRhizoxinica (Lackner, Moebius et al. 2011). These nucleic acid bindingpolypeptides comprise modules of about 31 to 33 amino acids that arebase specific. These modules display less than 40% sequence identitywith Xanthomonas TALE common repeats and present more polypeptidessequence variability. The different domains from the above proteins(modules, N and C-terminals) from Burkholderia and Xanthomonas areuseful to engineer new proteins or scaffolds having binding propertiesto specific nucleic acid sequences and may be combined to form chimericTALE-MBBBD proteins.

As examples, the present invention encompasses a method for engineeredT-cells in order to inactivate the expression of the genes encodingantigen markers such as CD38, CS1 and CD70 by using specificTALE-nucleases.

Particularly suitable for the realization of the invention,TALE-nucleases such as the ones in SEQ ID NO: 2-3;5-6;8-9, SEQ ID NO:64-65;67-68;70-71 and SEQ ID NO: 73-74;76-77;79-80 for respectivelyCD38, CS1 and CD70 genes. These specific TALE-nucleases, their sequencetarget and the protocol used are presented more thoroughly in thefollowing Examples 1-3.

Delivery Methods

The inventors have considered any means known in the art to allowdelivery inside cells or subcellular compartments of said cells thepolynucleotides expressing the endonucleases, their possibleco-effectors (e.g. guide RNA or DNA associated with Cas9 or Argonautenucleases) as well as the chimeric antigen receptors. These meansinclude viral transduction, electroporation and also liposomal deliverymeans, polymeric carriers, chemical carriers, lipoplexes, polyplexes,dendrimers, nanoparticles, emulsion, natural endocytosis or phagocytosepathway as non-limiting examples.

As a preferred embodiment of the invention, polynucleotides encoding theendonucleases of the present invention are transfected under mRNA formin order to obtain transient expression and avoid chromosomalintegration of foreign DNA, for example by electroporation. Theinventors have determined different optimal conditions for mRNAelectroporation in T-cell displayed in Table 1. The inventor used thecytoPulse technology which allows, by the use of pulsed electric fields,to transiently permeabilize living cells for delivery of material intothe cells (U.S. Pat. No. 6,010,613 and WO 2004/083379). Pulse duration,intensity as well as the interval between pulses can be modified inorder to reach the best conditions for high transfection efficiency withminimal mortality. Basically, the first high electric field pulses allowpore formation, while subsequent lower electric field pulses allow tomoving the polynucleotide into the cell. In one aspect of the presentinvention, the inventor describe the steps that led to achievementof >95% transfection efficiency of mRNA in T cells, and the use of theelectroporation protocol to transiently express different kind ofproteins in T cells. In particular the invention relates to a method oftransforming T cell comprising contacting said T cell with RNA andapplying to T cell an agile pulse sequence consisting of:

-   -   (a) one electrical pulse with a voltage range from 2250 to 3000        V per centimeter, a pulse width of 0.1 ms and a pulse interval        of 0.2 to 10 ms between the electrical pulses of step (a) and        (b);    -   (b) one electrical pulse with a voltage range from 2250 to 3000        V with a pulse width of 100 ms and a pulse interval of 100 ms        between the electrical pulse of step (b) and the first        electrical pulse of step (c); and    -   (c) 4 electrical pulses with a voltage of 325 V with a pulse        width of 0.2 ms and a pulse interval of 2 ms between each of 4        electrical pulses.

In particular embodiment, the method of transforming T cell comprisingcontacting said T cell with RNA and applying to T cell an agile pulsesequence consisting of:

-   -   (a) one electrical pulse with a voltage of 2250, 2300, 2350,        2400, 2450, 2500, 2550, 2400, 2450, 2500, 2600, 2700, 2800, 2900        or 3000V per centimeter, a pulse width of 0.1 ms and a pulse        interval of 0.2, 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10 ms between        the electrical pulses of step (a) and (b);    -   (b) one electrical pulse with a voltage range from 2250, of        2250, 2300, 2350, 2400, 2450, 2500, 2550, 2400, 2450, 2500,        2600, 2700, 2800, 2900 or 3000V with a pulse width of 100 ms and        a pulse interval of 100 ms between the electrical pulse of        step (b) and the first electrical pulse of step (c); and    -   (c) 4 electrical pulses with a voltage of 325 V with a pulse        width of 0.2 ms and a pulse interval of 2 ms between each of 4        electrical pulses.        Any values included in the value range described above are        disclosed in the present application. Electroporation medium can        be any suitable medium known in the art. Preferably, the        electroporation medium has conductivity in a range spanning 0.01        to 1.0 milliSiemens.

Viral Transduction

According to the present invention, the use of retroviral vectors andmore preferably of lentiviral vectors is particularly suited forexpressing the chimeric antigen receptors into the T-cells. Methods forviral transduction are well known in the art (Walther et al. (2000)Viral Vectors for Gene Transfer. Drugs. 60(2):249-271). Integrativeviral vectors allow the stable integration of the polynucleotides in theT-cells genome and to expressing the chimeric antigen receptors over alonger period of time.

Non Alloreactive T Cells

Although the method of the invention could be carried out in-vivo aspart of a gene therapy, for instance, by using viral vectors targetingT-cells in blood circulation, which would include genetic sequencesexpressing a specific rare-cutting endonuclease along with other geneticsequences expressing a CAR, the method of the invention is moregenerally intended to be practiced ex-vivo on cultured T-cellsobtainable from patients or donors. The engineered T-cells engineeredex-vivo can be either re-implanted into a patient from where theyoriginate, as part of an autologous treatment, or to be used as part ofan allogeneic treatment. In this later case, it is preferable to furtherengineer the cells to make them non-alloreactive to ensure their properengraftment. Accordingly, the method of the invention may includeadditional steps of procuring the T-cells from a donor and to inactivategenes thereof involved in MHC recognition and or being targets ofimmunosuppressive drugs such as described for instance in WO2013/176915.

T cell receptors (TCR) are cell surface receptors that participate inthe activation of T cells in response to the presentation of antigen.The TCR is generally made from two chains, alpha and beta, whichassemble to form a heterodimer and associates with the CD3-transducingsubunits to form the T-cell receptor complex present on the cellsurface. Each alpha and beta chain of the TCR consists of animmunoglobulin-like N-terminal variable (V) and constant (C) region, ahydrophobic transmembrane domain, and a short cytoplasmic region. As forimmunoglobulin molecules, the variable region of the alpha and betachains are generated by V(D)J recombination, creating a large diversityof antigen specificities within the population of T cells. However, incontrast to immunoglobulins that recognize intact antigen, T cells areactivated by processed peptide fragments in association with an MHCmolecule, introducing an extra dimension to antigen recognition by Tcells, known as MHC restriction. Recognition of MHC disparities betweenthe donor and recipient through the T cell receptor leads to T cellproliferation and the potential development of GVHD. It has been shownthat normal surface expression of the TCR depends on the coordinatedsynthesis and assembly of all seven components of the complex (Ashwelland Klusner 1990). The inactivation of TCRalpha or TCRbeta can result inthe elimination of the TCR from the surface of T cells preventingrecognition of alloantigen and thus GVHD.

Thus, still according to the invention, engraftment of the T-cells maybe improved by inactivating at least one gene encoding a TCR component.TCR is rendered not functional in the cells by inactivating TCR alphagene and/or TCR beta gene(s).

With respect to the use of Cas9/CRISPR system, the inventors havedetermined appropriate target sequences within the 3 exons encoding TCR,allowing a significant reduction of toxicity in living cells, whileretaining cleavage efficiency. The preferred target sequences are notedin Table 2 (+ for lower ratio of TCR negative cells, ++ for intermediateratio, +++ for higher ratio).

MHC antigens are also proteins that played a major role intransplantation reactions. Rejection is mediated by T cells reacting tothe histocompatibility antigens on the surface of implanted tissues, andthe largest group of these antigens is the major histocompatibilityantigens (MHC). These proteins are expressed on the surface of allhigher vertebrates and are called HLA antigens (for human leukocyteantigens) in human cells. Like TCR, the MHC proteins serve a vital rolein T cell stimulation. Antigen presenting cells (often dendritic cells)display peptides that are the degradation products of foreign proteinson the cell surface on the MHC. In the presence of a co-stimulatorysignal, the T cell becomes activated, and will act on a target cell thatalso displays that same peptide/MHC complex. For example, a stimulated Thelper cell will target a macrophage displaying an antigen inconjunction with its MHC, or a cytotoxic T cell (CTL) will act on avirally infected cell displaying foreign viral peptides.

Thus, in order to provide less alloreactive T-cells, the method of theinvention can further comprise the step of inactivating or mutating oneHLA gene.

The class I HLA gene cluster in humans comprises three major loci, B, Cand A, as well as several minor loci. The class II HLA cluster alsocomprises three major loci, DP, DQ and DR, and both the class I andclass II gene clusters are polymorphic, in that there are severaldifferent alleles of both the class I and II genes within thepopulation. There are also several accessory proteins that play a rolein HLA functioning as well. The Tap1 and Tap2 subunits are parts of theTAP transporter complex that is essential in loading peptide antigens onto the class I HLA complexes, and the LMP2 and LMP7 proteosome subunitsplay roles in the proteolytic degradation of antigens into peptides fordisplay on the HLA. Reduction in LMP7 has been shown to reduce theamount of MHC class I at the cell surface, perhaps through a lack ofstabilization (Fehling et al. (1999) Science 265:1234-1237). In additionto TAP and LMP, there is the tapasin gene, whose product forms a bridgebetween the TAP complex and the HLA class I chains and enhances peptideloading. Reduction in tapasin results in cells with impaired MHC class Iassembly, reduced cell surface expression of the MHC class I andimpaired immune responses (Grandea et al. (2000) Immunity 13:213-222 andGarbi et al. (2000) Nat. Immunol. 1:234-238). Any of the above genes maybe inactivated as part of the present invention as disclosed, forinstance in WO 2012/012667.

Method of Engineering Drug-Resistant T-Cells:

To improve cancer therapy and selective engraftment of allogeneicT-cells, drug resistance can be conferred to the engineered T-cells toprotect them from the toxic side effects of chemotherapy orimmunosuppressive agents. Indeed, the inventors have observed that mostpatients were treated with chemotherapy and immune depleting agents as astandard of care, prior to receiving T-cell immunotherapy. Also theyfound that they could take advantage of these treatments to help theselection of the engineered T-cells, either by adding chemotherapy drugsin culture media for expansion of the cells ex-vivo prior to treatment,or by obtaining a selective expansion of the engineered T-cells in-vivoin patients under chemotherapy or immunosuppressive treatments.

Also the drug resistance of T-cells also permits their enrichment in orex vivo, as T-cells which express the drug resistance gene, will surviveand multiply relative to drug sensitive cells. In particular, thepresent invention relates to a method of engineering allogeneic and drugresistance T-cells resistant for immunotherapy comprising:

-   -   (a) Providing a T-cell;    -   (b) Selecting at least one drug;    -   (c) Modifying T-cell to confer drug resistance to said T-cell;    -   (d) Expanding said engineered T-cell in the presence of said        drug, and optionally the preceding steps may be combined with        the steps of the methods as previously described.

Drug resistance can be conferred to a T-cell by inactivating one or moregene(s) responsible for the cell's sensitivity to the drug (drugsensitizing gene(s)), such as the hypoxanthine-guanine phosphoribosyltransferase (HPRT) gene (Genbank: M26434.1). In particular HPRT can beinactivated in engineered T-cells to confer resistance to a cytostaticmetabolite, the 6-thioguanine (6TG) which is converted by HPRT tocytotoxic thioguanine nucleotide and which is currently used to treatpatients with cancer, in particular leukemias (Hacke, Treger et al.2013). Another example if the inactivation of the CD3 normally expressedat the surface of the T-cell can confer resistance to anti-CD3antibodies such as teplizumab.

Drug resistance can also be conferred to a T-cell by expressing a drugresistance gene. Said drug resistance gene refers to a nucleic acidsequence that encodes “resistance” to an agent, such as achemotherapeutic agent (e.g. methotrexate). In other words, theexpression of the drug resistance gene in a cell permits proliferationof the cells in the presence of the agent to a greater extent than theproliferation of a corresponding cell without the drug resistance gene.A drug resistance gene of the invention can encode resistance toanti-metabolite, methotrexate, vinblastine, cisplatin, alkylatingagents, anthracyclines, cytotoxic antibiotics, anti-immunophilins, theiranalogs or derivatives, and the like.

Variant alleles of several genes such as dihydrofolate reductase (DHFR),inosine monophosphate dehydrogenase 2 (IMPDH2), calcineurin ormethylguanine transferase (MGMT) have been identified to confer drugresistance to a cell. Said drug resistance gene can be expressed in thecell either by introducing a transgene encoding said gene into the cellor by integrating said drug resistance gene into the genome of the cellby homologous recombination. Several other drug resistance genes havebeen identified that can potentially be used to confer drug resistanceto targeted cells (Takebe, Zhao et al. 2001; Sugimoto, Tsukahara et al.2003; Zielske, Reese et al. 2003; Nivens, Felder et al. 2004;Bardenheuer, Lehmberg et al. 2005; Kushman, Kabler et al. 2007).

DHFR is an enzyme involved in regulating the amount of tetrahydrofolatein the cell and is essential to DNA synthesis. Folate analogs such asmethotrexate (MTX) inhibit DHFR and are thus used as anti-neoplasticagents in clinic. Different mutant forms of DHFR which have increasedresistance to inhibition by anti-folates used in therapy have beendescribed. In a particular embodiment, the drug resistance geneaccording to the present invention can be a nucleic acid sequenceencoding a mutant form of human wild type DHFR (GenBank: AAH71996.1)which comprises at least one mutation conferring resistance to ananti-folate treatment, such as methotrexate. In particular embodiment,mutant form of DHFR comprises at least one mutated amino acid atposition G15, L22, F31 or F34, preferably at positions L22 or F31((Schweitzer, Dicker et al. 1990); International application WO94/24277; U.S. Pat. No. 6,642,043).

As used herein, “antifolate agent” or “folate analogs” refers to amolecule directed to interfere with the folate metabolic pathway at somelevel. Examples of antifolate agents include, e.g., methotrexate (MTX);aminopterin; trimetrexate (Neutrexin™); edatrexate;N10-propargyl-5,8-dideazafolic acid (CB3717); ZD1694 (Tumodex),5,8-dideazaisofolic acid (IAHQ); 5,10-dideazatetrahydrofolic acid(DDATHF); 5-deazafolic acid; PT523 (N alpha-(4-amino-4-deoxypteroyl)-Ndelta-hemiphthaloyl-L-ornithine); 10-ethyl-10-deazaaminopterin (DDATHF,lomatrexol); piritrexim; 10-EDAM; ZD1694; GW1843; Pemetrexate and PDX(10-propargyl-10-deazaaminopterin).

Another example of drug resistance gene can also be a mutant or modifiedform of ionisine-5′-monophosphate dehydrogenase II (IMPDH2), arate-limiting enzyme in the de novo synthesis of guanosine nucleotides.The mutant or modified form of IMPDH2 is a IMPDH inhibitor resistancegene. IMPDH inhibitors can be mycophenolic acid (MPA) or its prodrugmycophenolate mofetil (MMF). The mutant IMPDH2 can comprises at leastone, preferably two mutations in the MAP binding site of the wild typehuman IMPDH2 (NP_000875.2) that lead to a significantly increasedresistance to IMPDH inhibitor. The mutations are preferably at positionsT333 and/or 5351 (Yarn, Jensen et al. 2006; Sangiolo, Lesnikova et al.2007; Jonnalagadda, Brown et al. 2013). In a particular embodiment, thethreonine residue at position 333 is replaced with an isoleucine residueand the serine residue at position 351 is replaced with a tyrosineresidue.

Another drug resistance gene is the mutant form of calcineurin.Calcineurin (PP2B) is an ubiquitously expressed serine/threonine proteinphosphatase that is involved in many biological processes and which iscentral to T-cell activation. Calcineurin is a heterodimer composed of acatalytic subunit (CnA; three isoforms) and a regulatory subunit (CnB;two isoforms). After engagement of the T-cell receptor, calcineurindephosphorylates the transcription factor NFAT, allowing it totranslocate to the nucleus and active key target gene such as IL2. FK506in complex with FKBP12, or cyclosporine A (CsA) in complex with CyPAblock NFAT access to calcineurin's active site, preventing itsdephosphorylation and thereby inhibiting T-cell activation (Brewin,Mancao et al. 2009). The drug resistance gene of the present inventioncan be a nucleic acid sequence encoding a mutant form of calcineurinresistant to calcineurin inhibitor such as FK506 and/or CsA. In aparticular embodiment, said mutant form can comprise at least onemutated amino acid of the wild type calcineurin heterodimer a atpositions: V314, Y341, M347, T351, W352, L354, K360, preferably doublemutations at positions T351 and L354 or V314 and Y341. Correspondence ofamino acid positions described herein is frequently expressed in termsof the positions of the amino acids of the form of wild-type humancalcineurin heterodimer (GenBank: ACX34092.1).

In another particular embodiment, said mutant form can comprise at leastone mutated amino acid of the wild type calcineurin heterodimer b atpositions: V120, N123, L124 or K125, preferably double mutations atpositions L124 and K125. Correspondence of amino acid positionsdescribed herein is frequently expressed in terms of the positions ofthe amino acids of the form of wild-type human calcineurin heterodimer bpolypeptide (GenBank: ACX34095.1).

Another drug resistance gene is 0(6)-methylguanine methyltransferase(MGMT) encoding human alkyl guanine transferase (hAGT). AGT is a DNArepair protein that confers resistance to the cytotoxic effects ofalkylating agents, such as nitrosoureas and temozolomide (TMZ).6-benzylguanine (6-BG) is an inhibitor of AGT that potentiatesnitrosourea toxicity and is co-administered with TMZ to potentiate thecytotoxic effects of this agent. Several mutant forms of MGMT thatencode variants of AGT are highly resistant to inactivation by 6-BG, butretain their ability to repair DNA damage (Maze, Kurpad et al. 1999). Ina particular embodiment, AGT mutant form can comprise a mutated aminoacid of the wild type AGT position P140 (UniProtKB: P16455).

Another drug resistance gene can be multidrug resistance protein 1(MDR1) gene. This gene encodes a membrane glycoprotein, known asP-glycoprotein (P-GP) involved in the transport of metabolic byproductsacross the cell membrane. The P-Gp protein displays broad specificitytowards several structurally unrelated chemotherapy agents. Thus, drugresistance can be conferred to cells by the expression of nucleic acidsequence that encodes MDR-1 (NP_000918).

Drug resistance gene can also be cytotoxic antibiotics, such as ble geneor mcrA gene. Ectopic expression of ble gene or mcrA in an immune cellgives a selective advantage when exposed to the chemotherapeutic agent,respectively the bleomycine or the mitomycin C.

The T-cells can also be made resistant to immunosuppressive agents. Animmunosuppressive agent is an agent that suppresses immune function byone of several mechanisms of action. In other words, animmunosuppressive agent is a role played by a compound which isexhibited by a capability to diminish the extent and/or voracity of animmune response. As non-limiting example, an immunosuppressive agent canbe a calcineurin inhibitor, a target of rapamycin, an interleukin-2α-chain blocker, an inhibitor of inosine monophosphate dehydrogenase, aninhibitor of dihydrofolic acid reductase, a corticosteroid or animmunosuppressive antimetabolite. Classical cytotoxic immunosuppressantsact by inhibiting DNA synthesis. Others may act through activation ofT-cells or by inhibiting the activation of helper cells. The methodaccording to the invention allows conferring immunosuppressiveresistance to T cells for immunotherapy by inactivating the target ofthe immunosuppressive agent in T cells. As non-limiting examples,targets for immunosuppressive agent can be a receptor for animmunosuppressive agent such as: CD52, glucocorticoid receptor (GR), aFKBP family gene member and a cyclophilin family gene member.

In immunocompetent hosts, allogeneic cells are normally rapidly rejectedby the host immune system. It has been demonstrated that, allogeneicleukocytes present in non-irradiated blood products will persist for nomore than 5 to 6 days. Thus, to prevent rejection of allogeneic cells,the host's immune system must be effectively suppressed.Glucocorticoidsteroids are widely used therapeutically forimmunosuppression. This class of steroid hormones binds to theglucocorticoid receptor (GR) present in the cytosol of T cells resultingin the translocation into the nucleus and the binding of specific DNAmotifs that regulate the expression of a number of genes involved in theimmunologic process. Treatment of T cells with glucocorticoid steroidsresults in reduced levels of cytokine production leading to T cellanergy and interfering in T cell activation. Alemtuzumab, also known asCAMPATH1-H, is a humanized monoclonal antibody targeting CD52, a 12amino acid glycosylphosphatidyl-inositol-(GPI) linked glycoprotein(Waldmann and Hale, 2005). CD52 is expressed at high levels on T and Blymphocytes and lower levels on monocytes while being absent ongranulocytes and bone marrow precursors. Treatment with Alemtuzumab, ahumanized monoclonal antibody directed against CD52, has been shown toinduce a rapid depletion of circulating lymphocytes and monocytes. It isfrequently used in the treatment of T cell lymphomas and in certaincases as part of a conditioning regimen for transplantation. However, inthe case of adoptive immunotherapy the use of immunosuppressive drugswill also have a detrimental effect on the introduced therapeutic Tcells. Therefore, to effectively use an adoptive immunotherapy approachin these conditions, the introduced cells would need to be resistant tothe immunosuppressive treatment.

As a preferred embodiment of the above steps, said gene of step (b),specific for an immunosuppressive treatment, is CD52, and theimmunosuppressive treatment of step (d) comprises a humanized antibodytargeting CD52 antigen. As another embodiment, said gene of step (b),specific for an immunosuppressive treatment, is a glucocorticoidreceptor (GR) and the immunosuppressive treatment of step d) comprises acorticosteroid such as dexamethasone. As another embodiment, said targetgene of step (b), specific for an immunosuppressive treatment, is a FKBPfamily gene member or a variant thereof and the immunosuppressivetreatment of step (d) comprises FK506 also known as Tacrolimus orfujimycin. As another embodiment, said FKBP family gene member is FKBP12or a variant thereof. As another embodiment, said gene of step (b),specific for an immunosuppressive treatment, is a cyclophilin familygene member or a variant thereof and the immunosuppressive treatment ofstep (d) comprises cyclosporine.

In a particular embodiment of the invention, the genetic modificationstep of the method relies on the inactivation of two genes selected fromthe group consisting of CD52 and GR, CD52 and TCR alpha, CDR52 and TCRbeta, GR and TCR alpha, GR and TCR beta, TCR alpha and TCR beta. Inanother embodiment, the genetic modification step of the method relieson the inactivation of more than two genes. The genetic modification ispreferably operated ex-vivo using at least two RNA guides targeting thedifferent genes.

By inactivating a gene it is intended that the gene of interest is notexpressed in a functional protein form.

According to the present invention, the T-cells can be selected from thegroup consisting of inflammatory T-lymphocytes, cytotoxic T-lymphocytes,regulatory T-lymphocytes or helper T-lymphocytes. In another embodiment,said cell can be derived from the group consisting of CD4+T-lymphocytesand CD8+T-lymphocytes. They can be extracted from blood or derived fromstem cells. The stem cells can be adult stem cells, embryonic stemcells, more particularly non-human stem cells, cord blood stem cells,progenitor cells, bone marrow stem cells, induced pluripotent stemcells, totipotent stem cells or hematopoietic stem cells. Representativehuman cells are CD34+ cells. Prior to expansion and genetic modificationof the cells of the invention, a source of cells can be obtained from asubject through a variety of non-limiting methods. T-cells can beobtained from a number of non-limiting sources, including peripheralblood mononuclear cells, bone marrow, lymph node tissue, cord blood,thymus tissue, tissue from a site of infection, ascites, pleuraleffusion, spleen tissue, and tumors. In certain embodiments of thepresent invention, any number of T cell lines available and known tothose skilled in the art, may be used. In another embodiment, said cellcan be derived from a healthy donor, from a patient diagnosed withcancer or from a patient diagnosed with an infection. In anotherembodiment, said cell is part of a mixed population of cells whichpresent different phenotypic characteristics. In the scope of thepresent invention is also encompassed a cell line obtained from atransformed T-cell according to the method previously described.

As a further aspect of the invention, the T-cells according to theinvention may be further engineered, preferably genetically engineered,to enhance their activity and/or activation, especially by modulatingthe expression of proteins involved in overall T-cell regulation,referred to as “immune-checkpoints”.

Immune Check Points

It will be understood by those of ordinary skill in the art, that theterm “immune checkpoints” means a group of molecules expressed by Tcells. These molecules effectively serve as “brakes” to down-modulate orinhibit an immune response. Immune checkpoint molecules include, but arenot limited to Programmed Death 1 (PD-1, also known as PDCD1 or CD279,accession number: NM_005018), Cytotoxic T-Lymphocyte Antigen 4 (CTLA-4,also known as CD152, GenBank accession number AF414120.1), LAG3 (alsoknown as CD223, accession number: NM_002286.5), Tim3 (also known asHAVCR2, GenBank accession number: JX049979.1), BTLA (also known asCD272, accession number: NM_181780.3), BY55 (also known as CD160,GenBank accession number: CR541888.1), TIGIT (also known as IVSTM3,accession number: NM_173799), LAIR1 (also known as CD305, GenBankaccession number: CR542051.1, {Meyaard, 1997 #122}), SIGLEC10 (GeneBankaccession number: AY358337.1), 2B4 (also known as CD244, accessionnumber: NM_001166664.1), PPP2CA, PPP2CB, PTPN6, PTPN22, CD96, CRTAM,SIGLEC7 {Nicoll, 1999 #123}, SIGLEC9 {Zhang, 2000 #124; lkehara, 2004#125}, TNFRSF10B, TNFRSF10A, CASP8, CASP10, CASP3, CASP6, CASP7, FADD,FAS, TGFBRII, TGFRBRI, SMAD2, SMAD3, SMAD4, SMAD10, SKI, SKIL, TGIF1,IL10RA, IL10RB, HMOX2, IL6R, IL6ST, EIF2AK4, CSK, PAG1, SIT1, FOXP3,PRDM1, BATF {Quigley, 2010 #121}, GUCY1A2, GUCY1A3, GUCY1B2, GUCY1B3which directly inhibit immune cells. For example, CTLA-4 is acell-surface protein expressed on certain CD4 and CD8 T cells; whenengaged by its ligands (B7-1 and B7-2) on antigen presenting cells,T-cell activation and effector function are inhibited. Thus the presentinvention relates to a method of engineering T-cells, especially forimmunotherapy, comprising genetically modifying T-cells by inactivatingat least one protein involved in the immune check-point, in particularPD1 and/or CTLA-4 or any immune-checkpoint proteins referred to in Table3.

Engineered T-Cells Expressing Chimeric Antigen Receptors AgainstPathological Cells

The chimeric antigen receptors introduced into the T-cells according tothe invention can adopt different design such as single-chain ormulti-chain CARs. These different designs allow various strategies forimproving specificity and binding efficiency towards the targetedpathological cells. Some of these strategies are illustrated in thefigures of the present application. Single-chain CARs are the mostclassical version in the art. Multi-chain CAR architectures weredeveloped by the applicant as allowing modulation of the activity ofT-cells in terms of specificity and intensity. The multiple subunits canshelter additional co-stimulation domains or keep such domains at adistance, as well as other types of receptors, whereas classical singlechain architecture can sometimes be regarded as too much sensitive andless permissive to multispecific interactions.

Single-Chain CAR

Adoptive immunotherapy, which involves the transfer of autologousantigen-specific T cells generated ex vivo, is a promising strategy totreat viral infections and cancer. The T cells used for adoptiveimmunotherapy can be generated either by expansion of antigen-specific Tcells or redirection of T cells through genetic engineering (Park,Rosenberg et al. 2011). Transfer of viral antigen specific T cells is awell-established procedure used for the treatment of transplantassociated viral infections and rare viral-related malignancies.Similarly, isolation and transfer of tumor specific T cells has beenshown to be successful in treating melanoma.

Novel specificities in T cells have been successfully generated throughthe genetic transfer of transgenic T cell receptors or chimeric antigenreceptors (CARs) (Jena, Dotti et al. 2010). CARs are synthetic receptorsconsisting of a targeting moiety that is associated with one or moresignaling domains in a single fusion molecule. In general, the bindingmoiety of a CAR consists of an antigen-binding domain of a single-chainantibody (scFv), comprising the light and variable fragments of amonoclonal antibody joined by a flexible linker. Binding moieties basedon receptor or ligand domains have also been used successfully. Thesignaling domains for first generation CARs are derived from thecytoplasmic region of the CD3zeta or the Fc receptor gamma chains. Firstgeneration CARs have been shown to successfully redirect T cellcytotoxicity. However, they failed to provide prolonged expansion andanti-tumor activity in vivo. Signaling domains from co-stimulatorymolecules including CD28, OX-40 (CD134), and 4-1BB (CD137) have beenadded alone (second generation) or in combination (third generation) toenhance survival and increase proliferation of CAR modified T cells.CARs have successfully allowed T cells to be redirected against antigensexpressed at the surface of tumor cells from various malignanciesincluding lymphomas and solid tumors (Jena, Dotti et al. 2010).

In addition to the CAR targeting the antigen marker, which is common tothe pathological cells and the T-cells, such as CD38, it is envisionedto express further CARs directed towards other antigen markers notnecessarily expressed by the T-cells, so as to enhancing T-cellsspecificity.

Examples of chimeric antigen receptor that can be further expressed bythe T-cells to create multi-specific cells, are antigen receptorsdirected against multiple myeloma or lymphoblastic leukemia antigenmarkers, such as TNFRSF17 (UNIPROT 002223), SLAMF7 (UNIPROT 09N025),GPRC5D (UNIPROT Q9NZD1), FKBP11 (UNIPROT Q9NYL4), KAMP3, ITGA8 (UNIPROTP53708), and FCRL5 (UNIPROT Q68SN8).

As further examples, the antigen of the target can be from any clusterof differentiation molecules (e.g. CD16, CD64, CD78, CD96,CLL1, CD116,CD117, CD71, CD45, CD71, CD123 and CD138), a tumor-associated surfaceantigen, such as ErbB2 (HER2/neu), carcinoembryonic antigen (CEA),epithelial cell adhesion molecule (EpCAM), epidermal growth factorreceptor (EGFR), EGFR variant III (EGFRvIII), CD19, CD20, CD30, CD40,disialoganglioside GD2, ductal-epithelial mucine, gp36, TAG-72,glycosphingolipids, glioma-associated antigen, β-human chorionicgonadotropin, alphafetoprotein (AFP), lectin-reactive AFP,thyroglobulin, RAGE-1, MN-CA IX, human telomerase reverse transcriptase,RU1, RU2 (AS), intestinal carboxyl esterase, mut hsp70-2, M-CSF,prostase, prostase specific antigen (PSA), PAP, NY-ESO-1, LAGA-1a, p53,prostein, PSMA, surviving and telomerase, prostate-carcinoma tumorantigen-1 (PCTA-1), MAGE, ELF2M, neutrophil elastase, ephrin B2, CD22,insulin growth factor (IGF1)-I, IGF-II, IGFI receptor, mesothelin, amajor histocompatibility complex (MHC) molecule presenting atumor-specific peptide epitope, 5T4, ROR1, Nkp30, NKG2D, tumor stromalantigens, the extra domain A (EDA) and extra domain B (EDB) offibronectin and the A1. domain of tenascin-C(TnC A1) and fibroblastassociated protein (fap); a lineage-specific or tissue specific antigensuch as CD3, CD4, CD8, CD24, CD25, CD33, CD34, CD133, CD138, CTLA-4,B7-1 (CD80), B7-2 (CD86), GM-CSF, cytokine receptors, endoglin, a majorhistocompatibility complex (MHC) molecule, BCMA (CD269, TNFRSF 17), or avirus-specific surface antigen such as an HIV-specific antigen (such asHIV gp120); an EBV-specific antigen, a CMV-specific antigen, aHPV-specific antigen, a Lasse Virus-specific antigen, an InfluenzaVirus-specific antigen as well as any derivate or variant of thesesurface markers. Antigens are not necessarily surface marker antigensbut can be also endogenous small antigens presented by HLA class I atthe surface of the cells.

As examples, the present invention encompasses single-chain CARs whichtarget specifically cell surface marker, such as CD38, CS1 and/or CD70as described in the examples, together with an inactivation of the genesencoding respectively CD38, CS1 and/or CD70 in the cells expressing saidCARs.

As a specific example, the VH and VL chains of the scFv anti-CD38 shareat least 80%, preferably 90% and more preferably 95% of identity withrespectively SEQ ID NO:10 and 12 and SEQ ID NO: 11 and 13.

The same applies with respect topolynucleotide sequences using BLASTN.

Multi-Subunit CAR

Chimeric antigen receptors from the prior art introduced in T-cells havebeen formed of single chain polypeptides that necessitate serialappending of signaling domains. However, by moving signaling domainsfrom their natural juxtamembrane position may interfere with theirfunction. To overcome this drawback, the applicant recently designed amulti-chain CAR derived from FcεRI to allow normal juxtamembraneposition of all relevant signaling domains. In this new architecture,the high affinity IgE binding domain of FcεRI alpha chain is replaced byan extracellular ligand-binding domain such as scFv to redirect T-cellspecificity against cell targets and the N and/or C-termini tails ofFcεRI beta chain are used to place costimulatory signals in normaljuxtamembrane positions.

Accordingly, the CAR expressed by the engineered T-cell according to theinvention can be a multi-chain chimeric antigen receptor (CAR)particularly adapted to the production and expansion of engineeredT-cells of the present invention. Such multi-chain CARs comprise atleast two of the following components:

-   -   a) one polypeptide comprising the transmembrembrane domain of        FcεRI alpha chain and an extracellular ligand-binding domain,    -   b) one polypeptide comprising a part of N- and C-terminal        cytoplasmic tail and the transmembrane domain of FcεRI beta        chain and/or    -   c) at least two polypeptides comprising each a part of        intracytoplasmic tail and the transmembrane domain of FcεRI        gamma chain, whereby different polypeptides multimerize together        spontaneously to form dimeric, trimeric or tetrameric CAR.

According to such architectures, ligands binding domains and signalingdomains are born on separate polypeptides. The different polypeptidesare anchored into the membrane in a close proximity allowinginteractions with each other. In such architectures, the signaling andco-stimulatory domains can be in juxtamembrane positions (i.e. adjacentto the cell membrane on the internal side of it), which is deemed toallow improved function of co-stimulatory domains. The multi-subunitarchitecture also offers more flexibility and possibilities of designingCARs with more control on T-cell activation. For instance, it ispossible to include several extracellular antigen recognition domainshaving different specificity to obtain a multi-specific CARarchitecture. It is also possible to control the relative ratio betweenthe different subunits into the multi-chain CAR. This type ofarchitecture has been recently described by the applicant inPCT/US2013/058005 (WO2014/039523).

The assembly of the different chains as part of a single multi-chain CARis made possible, for instance, by using the different alpha, beta andgamma chains of the high affinity receptor for IgE (FcεRI) (Metzger,Alcaraz et al. 1986) to which are fused the signaling and co-stimulatorydomains. The gamma chain comprises a transmembrane region andcytoplasmic tail containing one immunoreceptor tyrosine-based activationmotif (ITAM) (Cam bier 1995).

The multi-chain CAR can comprise several extracellular ligand-bindingdomains, to simultaneously bind different elements in target therebyaugmenting immune cell activation and function. In one embodiment, theextracellular ligand-binding domains can be placed in tandem on the sametransmembrane polypeptide, and optionally can be separated by a linker.In another embodiment, said different extracellular ligand-bindingdomains can be placed on different transmembrane polypeptides composingthe multi-chain CAR. In another embodiment, the present inventionrelates to a population of multi-chain CARs comprising each onedifferent extracellular ligand binding domains. In a particular, thepresent invention relates to a method of engineering immune cellscomprising providing an immune cell and expressing at the surface ofsaid cell a population of multi-chain CAR each one comprising differentextracellular ligand binding domains. In another particular embodiment,the present invention relates to a method of engineering an immune cellcomprising providing an immune cell and introducing into said cellpolynucleotides encoding polypeptides composing a population ofmulti-chain CAR each one comprising different extracellular ligandbinding domains. In a particular embodiment the method of engineering animmune cell comprises expressing at the surface of the cell at least apart of FcεRI beta and/or gamma chain fused to a signal-transducingdomain and several part of FcεRI alpha chains fused to differentextracellular ligand binding domains. In a more particular embodiment,said method comprises introducing into said cell at least onepolynucleotide which encodes a part of FcεRI beta and/or gamma chainfused to a signal-transducing domain and several FcεRI alpha chainsfused to different extracellular ligand binding domains. By populationof multi-chain CARs, it is meant at least two, three, four, five, six ormore multi-chain CARs each one comprising different extracellular ligandbinding domains. The different extracellular ligand binding domainsaccording to the present invention can preferably simultaneously binddifferent elements in target thereby augmenting immune cell activationand function.

The present invention also relates to an isolated immune cell whichcomprises a population of multi-chain CARs each one comprising differentextracellular ligand binding domains.

The signal transducing domain or intracellular signaling domain of themulti-chain CAR of the invention is responsible for intracellularsignaling following the binding of extracellular ligand binding domainto the target resulting in the activation of the immune cell and immuneresponse. In other words, the signal transducing domain is responsiblefor the activation of at least one of the normal effector functions ofthe immune cell in which the multi-chain CAR is expressed. For example,the effector function of a T cell can be a cytolytic activity or helperactivity including the secretion of cytokines.

In the present application, the term “signal transducing domain” refersto the portion of a protein which transduces the effector signalfunction signal and directs the cell to perform a specialized function.

Preferred examples of signal transducing domain for use in single ormulti-chain CAR can be the cytoplasmic sequences of the Fc receptor or Tcell receptor and co-receptors that act in concert to initiate signaltransduction following antigen receptor engagement, as well as anyderivate or variant of these sequences and any synthetic sequence thatas the same functional capability. Signal transduction domain comprisestwo distinct classes of cytoplasmic signaling sequence, those thatinitiate antigen-dependent primary activation, and those that act in anantigen-independent manner to provide a secondary or co-stimulatorysignal. Primary cytoplasmic signaling sequence can comprise signalingmotifs which are known as immunoreceptor tyrosine-based activationmotifs of ITAMs. ITAMs are well defined signaling motifs found in theintracytoplasmic tail of a variety of receptors that serve as bindingsites for syk/zap70 class tyrosine kinases. Examples of ITAM used in theinvention can include as non-limiting examples those derived fromTCRzeta, FcRgamma, FcRbeta, FcRepsilon, CD3gamma, CD3delta, CD3epsilon,CD5, CD22, CD79a, CD79b and CD66d. In a preferred embodiment, thesignaling transducing domain of the multi-chain CAR can comprise theCD3zeta signaling domain, or the intracytoplasmic domain of the FcεRIbeta or gamma chains.

In particular embodiment the signal transduction domain of themulti-chain CAR of the present invention comprises a co-stimulatorysignal molecule. A co-stimulatory molecule is a cell surface moleculeother than an antigen receptor or their ligands that is required for anefficient immune response.

Ligand binding-domains can be any antigen receptor previously used, andreferred to, with respect to single-chain CAR referred to in theliterature, in particular scFv from monoclonal antibodies. Bispecific ormulti-specific CARs as described in WO 2014/4011988 are incorporated byreference.

Similarly as described before with respect to single-chain CARs, thepresent invention encompasses immune cells endowed with multi-chain CARswhich target specifically a cell surface marker such as CD38, CS1 orCD70. According to a preferred embodiment of the invention the CARsdescribed above are expressed in immune cells, whereas inactivation ofthe endogenous genes encoding said surface marker(s) is induced byexpression of a rare-cutting endonuclease.

Activation and Expansion of T Cells

The method according to the invention generally includes a further stepof activating and/or expanding the T-cells. This can be done prior to orafter genetic modification of the T cells, using the methods asdescribed, for example, in U.S. Pat. Nos. 6,352,694; 6,534,055;6,905,680; 6,692,964; 5,858,358; 6,887,466; 6,905,681; 7,144,575;7,067,318; 7,172,869; 7,232,566; 7,175,843; 5,883,223; 6,905,874;6,797,514; 6,867,041; and U.S. Patent Application Publication No.20060121005. According to these methods, the T cells of the inventioncan be expanded by contact with a surface having attached thereto anagent that stimulates a CD3 TCR complex associated signal and a ligandthat stimulates a co-stimulatory molecule on the surface of the T cells.

In particular, T cell populations may be stimulated in vitro such as bycontact with an anti-CD3 antibody, or antigen-binding fragment thereof,or an anti-CD2 antibody immobilized on a surface, or by contact with aprotein kinase C activator (e.g., bryostatin) in conjunction with acalcium ionophore. For co-stimulation of an accessory molecule on thesurface of the T cells, a ligand that binds the accessory molecule isused. For example, a population of T cells can be contacted with ananti-CD3 antibody and an anti-CD28 antibody, under conditionsappropriate for stimulating proliferation of the T cells. To stimulateproliferation of either CD4+ T cells or CD8+ T cells, an anti-CD3antibody and an anti-CD28 antibody. For example, the agents providingeach signal may be in solution or coupled to a surface. As those ofordinary skill in the art can readily appreciate, the ratio of particlesto cells may depend on particle size relative to the target cell. Infurther embodiments of the present invention, the cells, such as Tcells, are combined with agent-coated beads, the beads and the cells aresubsequently separated, and then the cells are cultured. In analternative embodiment, prior to culture, the agent-coated beads andcells are not separated but are cultured together. Cell surface proteinsmay be ligated by allowing paramagnetic beads to which anti-CD3 andanti-CD28 are attached (3×28 beads) to contact the T cells. In oneembodiment the cells (for example, 4 to 10 T cells) and beads (forexample, DYNABEADS® M-450 CD3/CD28 T paramagnetic beads at a ratio of1:1) are combined in a buffer, preferably PBS (without divalent cationssuch as, calcium and magnesium). Again, those of ordinary skill in theart can readily appreciate any cell concentration may be used. Themixture may be cultured for several hours (about 3 hours) to about 14days or any hourly integer value in between. In another embodiment, themixture may be cultured for 21 days. Conditions appropriate for T cellculture include an appropriate media (e.g., Minimal Essential Media orRPMI Media 1640 or, X-vivo 5, (Lonza)) that may contain factorsnecessary for proliferation and viability, including serum (e.g., fetalbovine or human serum), interleukin-2 (IL-2), insulin, IFN-g, 1L-4,1L-7, GM-CSF, -10,-2, 1L-15, TGFp, and TNF- or any other additives forthe growth of cells known to the skilled artisan. Other additives forthe growth of cells include, but are not limited to, surfactant,plasmanate, and reducing agents such as N-acetyl-cysteine and2-mercaptoethanoi. Media can include RPMI 1640, A1M-V, DMEM, MEM, a-MEM,F-12, X-Vivo 1, and X-Vivo 20, Optimizer, with added amino acids, sodiumpyruvate, and vitamins, either serum-free or supplemented with anappropriate amount of serum (or plasma) or a defined set of hormones,and/or an amount of cytokine(s) sufficient for the growth and expansionof T cells. Antibiotics, e.g., penicillin and streptomycin, are includedonly in experimental cultures, not in cultures of cells that are to beinfused into a subject. The target cells are maintained under conditionsnecessary to support growth, for example, an appropriate temperature(e.g., 37° C.) and atmosphere (e.g., air plus 5% CO2). T-cells that havebeen exposed to varied stimulation times may exhibit differentcharacteristics.

In another particular embodiment, said cells can be expanded byco-culturing with tissue or cells. Said cells can also be expanded invivo, for example in the subject's blood after administrating said cellinto the subject.

Therapeutic Applications

The T-cells obtainable by the different methods described above areintended to be used as a medicament for treating, among others, cancer,infections or immune diseases in a patient in need thereof.

Said treatment can be ameliorating, curative or prophylactic. It may beeither part of an autologous immunotherapy or part of an allogenicimmunotherapy treatment. By autologous, it is meant that cells, cellline or population of cells used for treating patients are originatingfrom said patient or from a Human Leucocyte Antigen (HLA) compatibledonor. By allogeneic is meant that the cells or population of cells usedfor treating patients are not originating from said patient but from adonor.

The T-cells engineered according to one of the previous methods may bepooled, frozen, and administrated to one or several patients. When theyare made non-alloreactive, they are available as an “off the shelf”therapeutic product, which means that they can be universally infused topatients in need thereof.

Said treatments are primarily intended to patients diagnosed withcancer, viral infection, autoimmune disorders or Graft versus HostDisease (GvHD). Cancers are preferably leukemias and lymphomas, whichhave liquid tumors, but may also concern solid tumors. Types of cancersto be treated with the CARs of the invention include, but are notlimited to, carcinoma, blastoma, and sarcoma, and certain leukemia orlymphoid malignancies, benign and malignant tumors, and malignanciese.g., sarcomas, carcinomas, and melanomas. Adult tumors/cancers andpediatric tumors/cancers are also included.

The present invention provides in Tables 4 to 14 with examples ofantigen markers, which can be targeted with the engineered-cells of theinvention for treating different types of cancer.

Preferred antigen markers used for the immunotherapy of the presentinvention are more particularly CD38, CD319 (CS1) and CD70.

The present T-cells, when armed with specific CARs directed againstpatient's own immune cells, especially T-cells, allow the inhibition orregulation of said cells, which is a key step for treating auto-immunedisease, such as rheumatoid polyarthritis, systemic lupus erythematosus,Sjogren's syndrome, scleroderma, fibromyalgia, myositis, ankylosingspondylitis, insulin dependent diabetes of type I, Hashimoto'sthyroiditis, Addison's disease, Crohn's disease, Celiac's disease,amyotrophic lateral sclerosis (ALS) and multiple sclerosis (MS).Accordingly the present invention encompass a method for treating animmune disease by directing engineered T-cells as previously describedagainst patient's own T-cells.

The above treatments can take place in combination with one or moretherapies selected from the group of antibodies therapy, chemotherapy,cytokines therapy, dendritic cell therapy, gene therapy, hormonetherapy, laser light therapy and radiation therapy.

The engineered T-cells as previously described, when they are maderesistant to chemotherapy drugs and immunosuppressive drugs that areused as standards of care, especially methotrexate and the combinationof fludarabine and Cyclophosphamide, are particularly suited fortreating various forms of cancer. Indeed, the present inventionpreferably relies on cells or population of cells, In this aspect, it isexpected that the chemotherapy and/or immunosuppressive treatment shouldhelp the selection and expansion of the engineered T-cells in-vivo.

In certain embodiments of the present invention, cells are administeredto a patient in conjunction with (e.g., before, simultaneously orfollowing) any number of relevant treatment modalities, including butnot limited to treatment with agents such as antiviral therapy,cidofovir and interleukin-2, Cytarabine (also known as ARA-C) ornataliziimab treatment for MS patients or efaliztimab treatment forpsoriasis patients or other treatments for PML patients. In furtherembodiments, the T cells of the invention may be used in combinationwith chemotherapy, radiation, immunosuppressive agents, such ascyclosporin, azathioprine, methotrexate, mycophenolate, and FK506,antibodies, or other immunoablative agents such as CAMPATH, anti-CD3antibodies or other antibody therapies, cytoxin, fludaribine,cyclosporin, FK506, rapamycin, mycoplienolic acid, steroids, FR901228,cytokines, and irradiation. These drugs inhibit either the calciumdependent phosphatase calcineurin (cyclosporine and FK506) or inhibitthe p70S6 kinase that is important for growth factor induced signaling(rapamycin) (Liu et al., Cell 66:807-815, 1 1; Henderson et al., Immun.73:316-321, 1991; Bierer et al., Citrr. Opin. mm n. 5:763-773, 93). In afurther embodiment, the cell compositions of the present invention areadministered to a patient in conjunction with (e.g., before,simultaneously or following) bone marrow transplantation, T cellablative therapy using either chemotherapy agents such as, fludarabine,external-beam radiation therapy (XRT), cyclophosphamide, or antibodiessuch as OKT3 or CAMPATH, In another embodiment, the cell compositions ofthe present invention are administered following B-cell ablative therapysuch as agents that react with CD20, e.g., Rituxan. For example, in oneembodiment, subjects may undergo standard treatment with high dosechemotherapy followed by peripheral blood stem cell transplantation. Incertain embodiments, following the transplant, subjects receive aninfusion of the expanded immune cells of the present invention. In anadditional embodiment, expanded cells are administered before orfollowing surgery. Said modified cells obtained by any one of themethods described here can be used in a particular aspect of theinvention for treating patients in need thereof against Host versusGraft (HvG) rejection and Graft versus Host Disease (GvHD); therefore inthe scope of the present invention is a method of treating patients inneed thereof against Host versus Graft (HvG) rejection and Graft versusHost Disease (GvHD) comprising treating said patient by administering tosaid patient an effective amount of modified cells comprisinginactivated TCR alpha and/or TCR beta genes.

According to one embodiment, said T cells of the invention can undergorobust in vivo T cell expansion upon administration to a patient, andcan persist in the body fluids for an extended amount of time,preferably for a week, more preferably for 2 weeks, even more preferablyfor at least one month. Although the T-cells according to the inventionare expected to persist during these periods, their life span into thepatient's body are intended not to exceed a year, preferably 6 months,more preferably 2 months, and even more preferably one month.

The administration of the cells or population of cells according to thepresent invention may be carried out in any convenient manner, includingby aerosol inhalation, injection, ingestion, transfusion, implantationor transplantation. The compositions described herein may beadministered to a patient subcutaneously, intradermally, intratumorally,intranodally, intramedullary, intramuscularly, by intravenous orintralymphatic injection, or intraperitoneally. In one embodiment, thecell compositions of the present invention are preferably administeredby intravenous injection.

The administration of the cells or population of cells can consist ofthe administration of 10⁴-10⁹ cells per kg body weight, preferably 10⁵to 10⁶ cells/kg body weight including all integer values of cell numberswithin those ranges. The cells or population of cells can beadministrated in one or more doses. In another embodiment, saideffective amount of cells are administrated as a single dose. In anotherembodiment, said effective amount of cells are administrated as morethan one dose over a period time. Timing of administration is within thejudgment of managing physician and depends on the clinical condition ofthe patient. The cells or population of cells may be obtained from anysource, such as a blood bank or a donor. While individual needs vary,determination of optimal ranges of effective amounts of a given celltype for a particular disease or conditions within the skill of the art.An effective amount means an amount which provides a therapeutic orprophylactic benefit. The dosage administrated will be dependent uponthe age, health and weight of the recipient, kind of concurrenttreatment, if any, frequency of treatment and the nature of the effectdesired.

In another embodiment, said effective amount of cells or compositioncomprising those cells are administrated parenterally. Saidadministration can be an intravenous administration. Said administrationcan be directly done by injection within a tumor.

Identification of Surface Antigen Marker Expressed on the Surface ofT-Cells, while being Overexpressed in Solid Tumors Involved intoDifferent Types of Cancer (Tables 5 to 13)

We used BioGPS microarray data from a panel of normal tissues (HumanU133A/GNF1H Gene Atlas) cancer microarray data that also can bedownloaded from BioGPS (Human Primary Tumors (U95)) uniprot data thatcontains the subcellular localization.

We drew the distribution of values coming from normal tissues anddetermined a threshold value of 5 for the relative expression.

We browsed all the genes assayed with microarrays (44.000 probesrepresenting about 13 000 genes) and checked their localization in themembrane (protein not referred to as being a membrane protein werediscarded). Expression in CD8+ T-cells was checked from the BioGPSdatabase. The genes were listed according to the type of cancer wherethe corresponding expression was the highest (Tables 5 to 13).

Identification of Surface Antigen Marker Expressed on the Surface ofT-Cells, while being Overexpressed in Different Liquid Blood Tumors(Table 14)

For that study, no RNA-seq data were available and thus we usedmicroarray data that were obtained from a large study from the MILEconsortium (Microarray Innovations in Leukemia), involving 11laboratories(http://www.ngrl.org.uk/wessex/downloads/tm08/TM08-S4-1_KenMills.pdf—Haferlachet al. 2010, http://www.ncbi.nlm.nih.gov/pubmed/20406941). This raw datainclude results for ALL (acute lymphoblastic leukemia), AML (acutemyelogenous leukemia), CLL (chronic lymphoblastic leukemia) and CML(chronic myelogenous leukemia) and MDS (myelodysplastic syndrome). Wealso used uniprot data for subcellular localization as usual.

We first drew the overall distribution of values from all genes on allstudied tissues. Then, to have an idea of the level necessary forexpression, we took a list of genes which are expressed in some liquidtumors and for which therapeutic antibodies are available (CD52, CD 20,CD33, CD19, CD25, CD44, CD47, CD96, CD116, CD117, CD135, TIM-3). Foreach gene, we looked at the value obtained in the tumor in which it isexpressed. Then, we computed the average for each tumor and gene pairfor which the gene seems to give a cell membrane protein (cell membranelocalization+ description of at least one transmembrane domain in theprotein). We discarded genes for which the expression in all the tissueswas below this threshold of 0.15. We listed and ranked in Table 14,those genes which relative expression in T-cells was above 0.2. Thus,Table 4 provides putative antigen marker candidates for targeting liquidtumor cells as per the invention, in particular for treating ALL, AML,CLL, CML and MDS.

Example of Steps to Engineer T-Cells According to the Invention forImmunotherapy

For a better understanding of the invention, it is provided below anexample of the steps to follow to produce T-cells directed againstleukemia CD38 positive cells:

-   -   1. Providing T-cells from a cell culture or from a blood sample        from one individual patient or from blood bank and activating        said T cells using anti-CD3/C28 activator beads (Dynabeads®).        The beads provide both the primary and co-stimulatory signals        that are required for activation and expansion of T cells.    -   2. Transducing said cells with a retroviral vector comprising a        transgene encoding a Chimeric antigen receptor consisting of the        fusion of CD3zeta activation domain, 4-1BB co-stimulation        domain, a transmembrane domain and a hinge from CD28 fused to a        sequence encoding the variable chain of an anti-CD38 antibody.        For security improvement of the transformed T-cell, a suicide        gene sensitive to rituximab may further be introduced as        described in WO 2013/153391 into the lentiviral vector separated        by T2A splitting sequences.    -   3. (Optionally) Engineering non alloreactive and/or resistant T        cells:        -   a) It is possible to Inactivate TCR alpha in said cells to            eliminate the TCR from the surface of the cell and prevent            recognition of host tissue as foreign by TCR of allogenic            and thus to avoid GvHD by following the protocols set forth            in WO 2013/176915.        -   b) It is also possible to inactive one gene encoding target            for an immunosuppressive agent or a chemotherapy drug to            render said cells resistant to immunosuppressive or            chemotherapy treatment to prevent graft rejection without            affecting transplanted T cells. In this example, target of            immunosuppressive agents is CD52 and immunosuppressive agent            is a humanized monoclonal anti-CD52 antibody (ex:            Alemtuzumab) as described in WO 2013/176915.    -   4. Gene Inactivation is performed by electroporating T-cells        with mRNA encoding specific TAL-endonuclease (TALEN™—Cellectis,        8 rue de la Croix Jarry, France). Inactivated T cells are sorted        using magnetic beads. For example, T cells still expressing the        targeted gene (e.g. CD38, CD70 and CD70) can be removed by        fixation on a solid surface, and inactivated cells are not        exposed of the stress of being passed through a column. This        gentle method increases the concentration of properly engineered        T-cells.    -   5. Expansion in vitro of engineered T-cells prior to        administration to a patient or in vivo following administration        to a patient through stimulation of CD3 complex. Before        administration step, patients can be subjected to an        immunosuppressive treatment such as CAMPATH1-H, a humanized        monoclonal anti-CD52 antibody.    -   6. Optionally exposed said cells with bispecific antibodies ex        vivo prior to administration to a patient or in vivo following        administration to a patient to bring the engineered cells into

proximity to a target antigen.

Functional Analysis of the Engineered T-Cells Electroporated with aMonocistronic mRNA Encoding for an Anti-CD38 Single Chain ChimericAntigen Receptor (CAR CD38):

To verify that genome engineering did not affect the ability of theengineered T-cells to present anti-tumor activity, especially whenprovided with a chimeric antigen receptor (CAR CD38), The engineeredT-cells were incubated for 4 hours with Daudi cells expressing CD38 ontheir surface. The cell surface upregulation of CD107a, a marker ofcytotoxic granule release by T lymphocytes (called degranulation) wasmeasured by flow cytometry analysis (Betts, Brenchley et al. 2003).

24 hours post electroporation, cells were stained with a fixableviability dye eFluor-780 and a PE-conjugated goat anti mouse IgG F(ab′)2fragment specific to assess the cell surface expression of the CAR onthe live cells. The vast majority of the live T-cells geneticallydisrupted for CD38, express the CAR on their surface. T cells wereco-cultured with Daudi (CD38⁺) cells for 6 hours and analyzed by flowcytometry to detect the expression of the degranulation marker CD107a attheir surface (Betts, Brenchley et al. 2003).

The results showed that CD38 disrupted T-cells kept the same ability todegranulate in response to PMA/ionomycin (positive control) or CD38+Daudi cells. CD107 upregulation is dependent on the presence of a CD38+.These data suggest that the genome engineering of the present T-cellshad no negative impact on the ability of T cells to mount a controlledanti-tumor response.

Example 1—Knock Out (KO) on CD38 Gene & Expression of Anti-CD38 Car

Presentation of the CD38 Target—Cyclic ADP Ribose Hydrolase

CD38 is a glycoprotein found on the surface of many immune cells,including multiple myeloma (MM) cells that express a high level of CD38in a large majority of patients. CD38 is a validated target for MM asmany studies have shown efficient killing of CD38+MM cells from patientsand CD38+MM cell lines using anti-CD38 mAbs by CDC and ADCC (Ellis, J.H. K. et al, Journal of Immunology, 1995, 155 (2), 925-937). Daratumumabis a therapeutic human CD38 monoclonal antibody which induces killing ofmultiple myeloma and other hematological tumors (De Weers, M. et al, JImmunol 2011 186:1840-1848). In some studies, it has been shown thatCD38 is also highly expressed by activated T cells (Sandoval-Montes 0 etal, 2005, Leukoc Biol. 77(4):513-21).

Expression of CD38 by T-Cells

The CD38 expression by T cells after CD3/CD28 beads and IL-2 stimulationwas analyzed by FACS every 3-4 days during 17 days. It was observed thatmore than 90% T cells express between day 6 and day 17 after activation(FIG. 10B).

Thus, in order to avoid killing of activated T cells by anti-CD38 CAR+ Tcells CD38 surface expression in T cells needs to be prevented. This maybe accomplished by the inactivation of the CD38 gene usingTALE-nucleases. TALEN is a trademark owned by the applicant (Cellectis,8 rue de la Croix Jarry, 75013 PARIS) designating customized format ofTAL nucleases.

Strategy for the CD38 Knock-Out (KO)

Heterodimeric TALE-nuclease targeting two 17-pb long sequences separatedby a 13-pb spacer within the CD38 gene were designed and produced. Eachhalf target is recognized by repeats of the half TALE-nucleases listedin the following Table 15 and FIG. 10A.

The repeats sequence of the left TALEN for the CD38ex1_T2 target wasNN-NI-NN-NN-NG-NN-NN-NN-NG-NG-NN-NN-HD-NN-NI-NG, and the one for theright TALEN was NN-NG-HD-HD-HD-HD-NN-HD-NI-NN-NG-NN-HD-HD-HD-NG.

Each TALE-nuclease construct was subcloned using restriction enzymedigestion in a mammalian expression vector under the control of the T7promoter. mRNA encoding TALE-nuclease cleaving CD38 were synthesizedfrom plasmids carrying the coding sequence downstream from the T7promoter.

Purified T cells activated during 72 hours with anti CD3/CD28 coatedbeads and recombinant IL-2 were transfected by electroporation(Cytopulse) with each of the 2 mRNAs (10 μg each) encoding both halfCD38ex1_T2 TALE-nucleases. To investigate, the CD38 KO, the percentageof CD38 negative T cells was assessed by flow cytometry at day 3, 6, 10and 13 after TALEN mRNA transfection. It was observed that 15% oftransfected T cells were CD38 deficient (FIG. 10 C) and this deficiencywas stable during 13 days after transfection.

Screening

CD38 TALENs will be transfected at day 4 after activation. 3 days afterthe CD38 deficient cells will be sorted by negative selection andtransfected 3 days after with anti-CD38 CAR mRNAs. The CAR moleculesgenerated will then be screened for expression and degranulationactivity toward target cell lines expression CD38 upon CAR mRNAtransient transfection. Target cell lines expressing differentexpression levels of CD38 (FIG. 11B) will be used for activity testing:

-   -   U266 CD38+ and U266 CD38− obtained by magnetic separation using        anti-CD38 microbeads    -   L363, a multiple myeloma cell line expressing intermediate        levels of CD38    -   Daudi, a cell line derived from Burkitt lymphoma expressing high        levels of CD38    -   K562, a cell line CD38 negative cell line derived from chronic        myelogenous leukemia.

This first screening will be followed by a second screening step inwhich a number of selected candidates will be tested for their abilityto induce degranulation, IFNγ release and specific cytotoxic activitytowards the selected target cell lines. Candidate selection will then benarrowed and some candidates selected for lentivirus vector productionand CAR activity will be assessed in CD38 KO T-cells stably expressingthe CARs.

Presentation of CS1 Target

Multiple myeloma (MM) is a B-cell malignancy characterized by theaberrant clonal expansion of plasma cells (PCs) within the bone marrow,with an estimated 21,700 new cases and 10,710 deaths from MM identifiedin the United States in 2012 (Siegel R, et al. Cancer J Clin 201262:10-29). In 2013, it has been estimated that 22,350 individuals willbe newly diagnosed with MM in the United States and 10,710 people willdie from it, accounting for 20% of the deaths from all hematologicmalignancies. Despite the use of proteasome inhibitors andimmune-modulating drugs, which have improved overall survival (PalumboA, et al. Leukemia 2009 23:449-456), MM remains an incurable malignancy(Podar K, et al. Leukemia 2009 23:10-24) for which novel therapeuticapproaches are urgently needed.

The cell surface glycoprotein CS1 (also referred in the literature asSLAMF7, CD319 or CRACC—NCBI Reference Sequence: NP_067004.3) is highlyand ubiquitously expressed on the surface of myeloma cells (Hsi E D, etal. Clin Cancer Res 2008 14:2775-84). CS1 is expressed at very lowlevels in the majority of immune effector cells, including naturalkiller (NK) cells, some subsets of T cells, and normal B cells, and isalmost undetectable on myeloid cells (Hsi E D, et al. Clin Cancer Res2008 14:2775-84). Notably, CS1 is negligibly expressed in humanhematopoietic stem cells (Hsi E D, et al. Clin Cancer Res 200814:2775-84), which can be used for stem cell transplantation to treathematologic malignancies, including MM. The functions of CS1 in MMremain incompletely understood, and it has been documented that CS1 mayplay a role in myeloma cell adhesion, clonogenic growth, andtumorigenicity (Benson D M Jr, et al. J Clin Oncol 2012 30:2013-5; Tai YT, et al. Blood 2009 113:4309-18).

Structure of the CAR Anti-CS1

The same structures V1, V2 and V3 are designed such as in the Example 1for the anti-CD38 antigen target single-chain CAR, with the samecomponents in terms of hinge, transmembrane domain, co-activation andtransduction domains (such as depicted in the FIG. 11A and sequencesshown in Table 18).

In Table 19 are presented the VH and VL chains of scFv anti-CS1. SEQ IDNO:38-40-42-44-46 and SEQ ID NO:39-41-43-45-47 correspond torespectively the VH chain and the VL chain of the murine scFv Luc63,Luc90, Luc34, LucX1 and LucX2.

In Table 20 are presented anti-CS1 CARs with the above scFv; these CARsbeing based on the versions V1, V2 and V3 of FIG. 11A, whereinrespectively the short FcERγ hinge, the medium hinge CD8a hinge and thelong IgG1 hinge are used. The underlined parts correspond to the scFv VHand VL chains bound by a linker.

Strategy for CAR CS1+ and KO CS1 Engineering

CS1 is expressed at high levels in plasmacytoid cells from patients withMultiple Myeloma, making this an interesting target for CAR development.T-cells, especially the CD8 subset, express low levels of CS1, which isa drawback for T-cell CAR development, since they could be killed whenexpressing an anti-CS1 CAR.

In this example we assessed the activity of the Luc90-v2 CAR (sequenceshown in Table 20) in human T-cells that were either mock transfected,or transfected with a TALEN targeting the CS1 (SLAM F7) gene, to see ifthe CAR activity was enhanced when the CS1 gene was disrupted in CAR+T-cells. The course of the experiment is shown in the FIG. 12 .

T-cells were purified from buffy-coat samples and activated usingCD3/CD28-coated beads. Cells were co-transfected 72 h after activationwith 10 μg of mRNA encoding the TO1_left TAL and 10 μg of the mRNAencoding the T01_right TAL. Sequences of the TALs are shown in thefollowing Table 21 and the plasmid constructs (T01, T02 and T03) withthe TAL repeats shown in FIG. 13 .

FIG. 14 shows the target location for the TALs T01, T02 and T03 withinthe CS1 (SLAMF7) gene: T01 and T02 target the exon 1 (FIG. 14A), whereasT03 targets the exon 2 (FIG. 14B).

3 days after TALEn transfection, cells were transduced with arecombinant lentiviral vector driving expression of the L90-v2 CAR offan EF1a promoter. The lentiviral vector is built in a way that CARexpression is coupled with BFP expression (Blue Fluorescent Protein)through a ribosomal skip peptide. The L90-v2 CAR is constituted by anextracellular binding domain recognizing the CS1 target (scFv L90)followed by hinge and transmembrane regions derived from the hCD8αprotein. The intracellular portion of the molecule contains a41BB-derived costimulatory domain, followed by the CD3γ signaling domain(sequences displayed in previous Table 18-19-20 for individualcomponents, scFv and CAR sequences respectively).

Transduction efficiency was assessed 6 days after transduction by flowcytometry, by following BFP expression. Cells were also stained withanti-CD8 and anti-CS1 antibodies.

Results

CAR CS1+ Expression

The results from FIG. 16 show that the transduction efficiencies arehigher in mock transfected cells than in cells that have beentransfected with TALEn targeting the CS1 gene. This is probably due tospecific cell killing of non-transduced CS1-expressing T-cells, whilethis population is not affected when the cells no longer express CS1 asa consequence of TALEN-driven gene disruption.

No significant differences in CS1 levels are observed at this timepointbetween TALEN or mock transfected cells (negative control-transfectionwithout plasmid), since CS1 levels decrease over time after initialactivation of T-cells. On the other hand, a significant decrease in the% of CD8+ cells is observed in mock transfected CAR expressing cellscompared to TALEN transfected CAR+ cells, indicating that a highproportion of CD8+ cells has been eliminated by the CAR+ T-cells.

Cytotoxic Activity Assessment

The cytotoxic activity of these cells was evaluated 8 days after CARtransduction, by co-culturing the same amount of T-cells either with acell line expressing CS1 (L363 cells) or a negative control cell linelacking expression of CS1 (MOLM13). The viability of the target celllines was measured by flow cytometry 4 h after starting cellco-cultures. The results shown in FIG. 15A show reduced cell viabilityof CS1(+) cells when they were co-cultured with CAR+ T-cells, while noimpact on CS1(−) cell viability was observed. The specific cell lysiswas calculated using the flow cytometry data, and it was 2-times higherwhen T-cells have been transfected with TALEn targeting the CS1 geneprior to CAR transduction (FIG. 15B). It should be considered that theimpact might be even higher, since the amount of CAR+ T-cells present inthe co-cultures is higher when the cells were mock transfected (see flowcytometry data from FIG. 16 ). The results from the experiment are thefollowing:

-   -   for the Mock/NTD sample, the % of BFP+ cells is 0.1% and the        amount of CD8+ cells is 53.9%;    -   for the TALEn/NTD sample, the % of BFP+ cells is 0.2% and the        amount of CD8+ cells is 49.5%;    -   for the Mock/L90-2 sample, the % of BFP+ cells is 94% and the        amount of CD8+ cells is 1.8%;    -   for the TALEn/L90-2 sample, the % of BFP+ cells is 61% and the        amount of CD8+ cells is 8.3%.    -   Transduction efficiencies are higher in mock transfected cells        than in cells that have been transfected with TALEn targeting        the CS1 gene (NTD: not transduced).

Reactivation after Transduction

In order to confirm that the CS1 gene has been disrupted in TALEntransfected T-cells, the different samples were reactivated withCD3/CD28 beads at D11 after transduction. 72 h after reactivation cellswere stained with anti-CD8 and anti-CS1 antibodies and expressionanalyzed by flow cytometry.

FIG. 17 shows the transduction efficiencies and CD8/CS1 expressionlevels in each sample. As shown in the lower panel, an increase in CS1levels upon re-activation is observed in mock transfected cells, while alow amount of cells are able to express CS1 in the TALEn transfectedpopulations.

The results from the experiment are the following:

-   -   for the Mock/NTD sample, the % of BFP+ cells is 0.01%, CS1 is        expressed in 65.2% of cells, and the amount of CD8+ cells is        80.7%;    -   for the TALEn/NTD sample, the % of BFP+ cells is 0.2%, the CS1        is expressed in 9.7% of cells and the amount of CD8+ cells is        78.8%;    -   for the Mock/L90-2 sample, the % of BFP+ cells is 94%, the CS1        is expressed in 37.5% of cells and the amount of CD8+ cells is        16%.    -   for the TALEn/L90-2 sample, the BFP intensity is 61%, the CS1        expression is 8.5% and the CD8 expression is 68.5%.

An increase in CS1 levels upon re-activation is observed in mocktransfected cells, while a low amount of cells are able to express CS1in the TALEn transfected populations.

Altogether, these results indicate that the CS1 gene is disrupted inTALEn transfected T-cells, and that this enhances the cytotoxic activityof anti-CS1 CAR+ cells, mainly by preserving the cytotoxic CD8+ T-cells.

Example 3: CD70 Target

Presentation of CD70 Target

The CD70 is a cytokine that binds to CD27 and is part of the TNF family(Goodwin R. G. et al, 1993, Cell 73:447-456). This protein has a role inadaptive T cell responses, induces the proliferation of costimulatedT-cells and enhances the generation of cytolytic T-cells. Its accessionnumber is P32970 (Uniprot). Some studies such as in Schürch, C. et al.(J. Clin. Invest., 2012; doi:10.1172/JCI45977) suggest that blockingCD27-CD70 interactions could help treat chronic myelogenous leukemia(CML).

Strategy for CD70 KO

The same strategy for the KO of CD70 gene will be performed such as inExample 1 and Example 2. Heterodimeric TALE-nuclease targeting two 49-pblong sequences separated by a 15 pb spacer within the CD70 gene and oneTALE-nuclease targeting a 57-pb long sequence separated by a 23 pbspacer were designed and produced. Each half target is recognized byrepeats of the half TALE-nucleases listed in the following Table 22.

Strategy for the Expression of Anti-CD70 CAR

The same strategy for expressing a CAR anti-CD70 will be performed suchas in Example 1 and in Example 2.

The same structures V1, V2 and V3 are designed such as in the Example1-2 with the same components in terms of signal peptide, linker betweenthe VH and VL chains, transmembrane domain, co-activation andtransduction domains (general architectures shown in FIG. 11A, andsequences for individual components shown in Table 18). Only the hingediffers between the 3 versions V1, V2 and V3, wherein respectively theshort FcERγ hinge, the medium hinge CD8a hinge and the long IgG1 hingeare used.

In Table 23 are presented VH and VL chain of scFv anti-CD70. SEQ IDNO:81-82, 85-86, 89-90 and SEQ ID NO:83-84,87-88, 91-92 correspond torespectively the VH chain and the VL chain of the scFv Ab4, Ab8 fromAMGEN and 1F6 from Seattle Genetics.

In Table 24 are presented the anti-CD70 CARs with the above scFv; theseCARs being based on the versions V1, V2 and V3 according to FIG. 11A,wherein respectively a short FcEγ hinge, a medium hinge CD8 and a longIgG1 hinge are used.
